On (fictional) universes and the insanity of IP ownership

History and cultural heritage as a source of inspiration is truly amazing in many ways. The fastness of it, the depth and richness. The endless possibilities in analyzing histories, comparing the past and the present or juxtaposing those. You can interpret it endlessly and use it as a foundation for study, fiction, research and art. This makes it very great, but not unique in the complete body of work we call culture. What makes it so special is that, as property in the public domain, no part of history can be owned by a single person or cooperation.

It may seem really straightforward to you that when I take an era in history, say the French revolution and write a narrative history of this era, that I do not automatically own the rights to that historical event. I have copyright of my work, but the foundation on which this work has been build does not default into my care completely. I can’t bar people from entertaining the same narrative or a completely new interpretation of the French revolution just because I wrote something about it in a particular context.
Now where am I going with this?
